Abstract
The invention discloses a fluid pressure safety valve, and belongs to the technical field of pressure safety valves. When fluid mediums flow into a medium flowing-in hole, a piston can rise to a certain height and an original medium flowing-out hole in a blocking state is opened if pressure exceeds a setting highest limit, and therefore the purpose of pressure relieving is achieved. At the same time, after the piston rises to a valid sensing distance of a magnetic induction type proximity sensor, the magnetic induction type proximity sensor sends out corresponding control signals or alarming signals. The fluid pressure safety valve has the advantages of being simple in structure, good in manufacturability, low in cost and reliable in work.
Description
Technical field
The present invention relates to a kind of pressure security valve technology, specifically a kind of hydrodynamic pressure safety valve.
Background technique
In electromechanical equipment, the working pressure of convection cell requires very strict, in case pressure surpasses the peak of allowing, might cause equipment to work, and even can cause serious accident.At present, although the safety valve that is used for the limit fluid maximum pressure structurally face is not quite similar, but, general complex structure, anufacturability is relatively poor, cost the is higher defective of all existing, simultaneously, the output electrical signals of existing safety valve is generally to adopt the sensitive switch of contact is arranged, and has the sensitive switch of contact easily to be subject to the impact of surrounding environment and foreign matter, so, also have the insecure defective of work.
Summary of the invention
The present invention is directed to the existing complex structure of existing hydrodynamic pressure safety valve, anufacturability is relatively poor, cost is higher and work insecure defective, the invention provides a kind of novel hydrodynamic pressure safety valve, it is simple in structure, anufacturability is better, cost is lower.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: this invention comprises that housing, piston, spring, magnetic induction type proximity detector, bottom, MEDIA FLOW hand-hole, MEDIA FLOW are portalled, vent.This invention is provided with a top and is provided with the rectangular case that the emerging formula proximity detector of magnetic strength, bottom are provided with bottom, the inside of described housing is fixed with spring and piston successively, port position at housing is installed bottom, be provided with the MEDIA FLOW hand-hole in the middle of described bottom, on the outer wall of housing, be respectively equipped with the mutually penetrating MEDIA FLOW of enclosure interior and portal and vent.
Working principle of the present invention is, when flowing medium is linked into the MEDIA FLOW hand-hole, if pressure surpasses the highest limit of setting, piston will rise to certain height, and will be originally by the MEDIA FLOW of blocked state portal open, so, reach the purpose of pressure release, simultaneously, after piston rose to magnetic induction type proximity detector actual induction distance, the magnetic induction type proximity detector sent the signal of corresponding control or warning.
Beneficial effect: have structure of the present invention and working principle to find out, that the present invention has advantages of is simple in structure, anufacturability better, cost is lower and reliable operation, can effectively overcome the existing existing defects of hydrodynamic pressure safety valve.
Description of drawings
Accompanying drawing 1 is structure principle chart of the present invention;
Shown in figure: 1, housing; 2, piston; 3, spring; 4, magnetic induction type proximity detector; 5, bottom; 6, MEDIA FLOW hand-hole; 7, MEDIA FLOW is portalled; 8, vent.
Embodiment
In the drawings, this invention comprises that housing 1, piston 2, spring 3, magnetic induction type proximity detector 4, bottom 5, MEDIA FLOW hand-hole 6, MEDIA FLOW portal 7, vent 8.This invention is provided with a top and is provided with the rectangular case 1 that the emerging formula proximity detector 4 of magnetic strength, bottom are provided with bottom 5, the inside of described housing 1 is fixed with spring 3 and piston 2 successively, port position at housing 1 is installed bottom 5, be provided with MEDIA FLOW hand-hole 6 in the middle of described bottom 5, on the outer wall of housing 1, be respectively equipped with the mutually penetrating MEDIA FLOW in housing 1 inside and portal 7 and vent 8.
When flowing medium is linked into MEDIA FLOW hand-hole 6, if pressure surpasses the highest limit of setting, piston 2 will rise to certain height, and will be originally by 7 openings of portalling of the MEDIA FLOW of blocked state, so, reach the purpose of pressure release, simultaneously, after piston 2 rose to magnetic induction type proximity detector 4 actual induction distances, magnetic induction type proximity detector 4 sent the signal of corresponding control or warning.
